Abstract
A power converter module includes a multilayer printed circuit board, a switching device, a magnetic core element and a winding via. The multilayer printed circuit board has a first surface, a second surface and an inside layer. The multilayer printed circuit board includes a plurality of copper layers. The magnetic core element is disposed in the inside layer and includes a hole. One end of the winding via is electrically connected to the switching device, and the other end of the winding via is electrically connected to the second surface. The winding via penetrates through the hole and forms a magnetic assembly. An amount of the copper layers on a first side of the magnetic core element close to the first surface of the multilayer printed circuit board is at least two more than a second side of the magnetic core element.
